SASH-LOCK.

SPECIFICATION forming part of Letters Patent No. 360,015, dated March 29, 1887.

Application filed August 5, 1886. Serial No. 210,076. (No model.)

To all whom it may concern.-

Be it known that I, DANIEL B. HART, of the city of Passaic, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Sash-Locks; and I do hereby declare that the following is a full, clear, and exact description oftheinvention reference being had to the accompanying drawi ngs,'and to the letters of reference thereon, which form part of this specification.

My invention relates to locks especially applicable for fastening sashes, which may also be used on other structures where it is desired to have a convenient means for fastening the same in varying positions, and has for its object a simple and convenient bolt or catch adapted to engage with a suitable bearing to hold the structures in the desired position. I accom plish these objects by the mechanism illustrated in the accompanying drawings, which show my invention as applied to a window-sash.

Figure 1 is an elevation of portions of two window-sashes,showing my invention applied thereto. Fig. 2is a vertical section of Fig. 1. Fig. 3isavertical section of my lock on alarger scale, to show the parts more clearly. Fig. dis a front view of the bolt-case, with the thumbpiece of the bolt-pull handle broken away. Fig. 5 is a sectional plan on the line of the uppersurface of the bolt 1). Fig. 6 is a View of the bolt, and Fig. 7 is a view of the key or bolt-pull.

Similar letters of reference indicate like parts in all the drawings.

Ais the upper and B the lower sash of window.

To the face of the upper sash is secured a ratchet-strip, a, preferably made strong of metal, and this may be screwed to the face of the sash, if there is room, in a suitable position to engage with the bolt Z),- or it may be made of such size as to be countersunk into the sash, which will be the most secure manner of attaching it.

On the upper part of the lower sash, at a suitable point to cause the bolt to engage properly with the ratchet-strip a, I attach the bolt 1). This bolt 1) is disposed in a suitable case, which may consist of two partsthe bolt-case proper, c, and its 'front dwhich are conveniently made of metal, the front (Z being secured to the case by the screw (2. The bolt-case cis provided with a suitable channel to receive the bolt 1), so that it will move smoothly and easily therein, having sufficient play to be projected outward to the required distance to engage with the ratchet-picce a and to be retracted within the case Without projecting beyond its face.

For projecting and retracting the bolt,I provideaboltkey or pullof peculiarconstruction. It consists of a head, 6, stem f, shoulders i and j, bearing-g, and thumb piece or handle 71. The shoulderj is most clearly shown in Fig. 7. In the instance of my invention shown in the drawings,the bolt-keyis set into thelower left hand corner of the bolt 6. In this a recess is cut out of sufficient size to receive the head 6 of the key, and a smaller portion is cut away for the stem f. Next to the stem f is the enlarged part or shoulder '13, then the bearing 9, and then a reduced portion, j, corresponding in size to the shoulder partt', and then the handle h. In the front piece, cl, a slot, 7;, is pro vided, of suitable size to permit the passage thereth rough of the bearing The parts 6, f, i, and j are round to permit of easy rotation, the diameter of the parts 2' and j corresponding to the width of the bearing 9, so as to turn and move snugly in the slot 7t and prevent rattling in operating the bolt.

In Fig. 3 the bolt 1) is shown projected and locking the sashes,while the handle his turned vertically, permitting the withdrawal of the bolt. The bolt and bolt-key can now be with drawn until the bearingg has passed out ofthe bolt-case front cl, as shown by the dotted lines in Fig. 5, and then by turning the handle it to a horizontal position the bolt I) is secured within its case and the sashes are disconnected. IVhen it is desired to lock them again, the handle h is turned to the vertical position, bringing the bearing gcoincidentwith the slot k,and by pushing it in the bolt will be projected into the opposite ratchet. By then turning the handle it to the horizontal position the bearing will rest against the inner face of the casefront d, as shown in Fig. 5, and prevent the retraction of the bolt.

The advantage of securing the bolt-key to the lower left-hand corner of the bolt is that then the edges of the slot will be coincident with the side of the bolt-channel, and all that is necessary to withdraw the bolt is to turn up the handle until the bearing strikes the side,

when it will be in position coincident with the slot is, and may be withdrawn without the trouble of -finding the slot, or the use of any other guide. Of course the same result may be produced by reversing the parts; butIhave found the arrangement described to be as convenient as any other.

It will be seen that by means of this sashloek the sashes may be fastened when the window is entirely closed by adjusting the ratchet in such position that one of its notches.-the lower one-will engage with the bolt when the window is closed; and the sashes may also be fastened together when the window is more or less open, according to the particular notch made to engage with the bolt, so that the window may be securely fastened when open for ventilating or for other purposes without any risk of having the same further opened, except by breaking the lock or the glass.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A sash-lock consisting of the engagingpiece a, the bolt 12, and a suitable case for said bolt, in combination with the key, recessed into said bolt and provided with the bearing 9, adapted to engage-with the inner face of the bolt-case to look the bolt in position when projected, and with the outer face of the case to lock the bolt in position when retracted, substantially as described.

2. In a sash-look, the bolt 11 and a suitable case for the same, in combination with the key provided with the bearing 5/, adapted to engage with the inner face of the ease and lock the bolt in position when projected, substantially as described. DANIEL B. HART.
